What's the difference in how you can access Map fields?
Hello,
I have some trouble accessing elixir maps, I didn’t figure out the way to because there is 3 ways :
body = %{
test: value
}
Do we access the "test field by :
- body[“test”
or - body[:test]
or
body.test
what is the difference between the 3 ways ?
thanks

Hey @xgeek116
body["test"]
This one won’t work, because it looks for a key that is "test". "test" is a string, but your key is :test which is an atom.
body[:test]
This will work and return the value. If you put in a key that does not exist in the map like body[:hello] it will return nil.
body.test
This will also work and return the value. If you use a key that does not exist like body.hello it will raise an exception.
